Host System Administration
|
|
==========================
|
|
include::attributes.txt[]
|
|
|
|
{pve} is based on the famous https://www.debian.org/[Debian] Linux
|
|
distribution. That means that you have access to the whole world of
|
|
Debian packages, and the base system is well documented. The
|
|
https://debian-handbook.info/download/stable/debian-handbook.pdf[Debian
|
|
Administrator\'s Handbook] is available online, and provides a
|
|
comprehensive introduction to the Debian operating system (see
|
|
xref:Hertzog13[]).
|
|
|
|
A standard {pve} installation uses the default repositories from
|
|
Debian, so you get bug fixes and security updates through that
|
|
channel. In addition, we provide our own package repository to roll
|
|
out all {pve} related packages. This includes updates to some
|
|
Debian packages when necessary.
|
|
|
|
We also deliver a specially optimized Linux kernel, where we enable all
|
|
required virtualization and container features. That kernel includes
|
|
drivers for http://zfsonlinux.org/[ZFS], and several hardware drivers.
|
|
For example, we ship Intel network card drivers to support their
|
|
newest hardware.
|
|
|
|
The following sections will concentrate on virtualization related
|
|
topics. They either explains things which are different on {pve}, or
|
|
tasks which are commonly used on {pve}. For other topics, please refer
|
|
to the standard Debian documentation.
|
|
|
|
System requirements
|
|
-------------------
|
|
|
|
For production servers, high quality server equipment is needed. Keep
|
|
in mind, if you run 10 Virtual Servers on one machine and you then
|
|
experience a hardware failure, 10 services are lost. {pve}
|
|
supports clustering, this means that multiple {pve} installations
|
|
can be centrally managed thanks to the included cluster functionality.
|
|
|
|
{pve} can use local storage (DAS), SAN, NAS and also distributed
|
|
storage (Ceph RBD). For details see xref:chapter-storage[chapter storage].
